Hiring a General Contractor in San Francisco, California
California requires contractors to be licensed by the Contractor's State License Board (CSLB). General contractors in California may hold a General Engineering Contractor license or a General Building Contractor license—each covers different scopes of work. Before hiring, verify the contractor's license status and type on the CSLB website. You can search by license number or business name to confirm their credentials and check complaint disclosure.
Most construction work in California requires a building permit from your local building department. Permit requirements vary by city and county, so check with the San Francisco Building Department to understand what applies to your project. A licensed contractor can guide you through permit requirements, but it's your responsibility to ensure permits are obtained before work begins.
When selecting a contractor, ask about their licensing classification, which projects they've completed, whether they perform work in-house or subcontract portions, and their experience with your specific project type. Request a detailed written contract that covers scope, timeline, materials, and cost before signing.
How do I verify a contractor's California license?
Visit the CSLB website and search by contractor license number or business name. You can verify their license status and view complaint disclosure information. A valid license number contains only numbers and no more than 8 digits. [4]
What are the main contractor license types in California?
California offers a General Engineering Contractor license and a General Building Contractor license, among specialty licenses. Each covers different types of work. Check with the CSLB to understand which license applies to your project. [1]
Do I need a building permit for my project in San Francisco?
According to California Building Standards Code, most building, construction, alteration, repair, and demolition work requires a separate permit. Code requirements vary by city and county. Contact the San Francisco Building Department to determine what permits your specific project needs. [3]
What should I ask a contractor before hiring?
Ask about their license type and status, experience with similar projects, whether they perform work themselves or subcontract, insurance coverage, and get a detailed written contract covering scope, timeline, materials, and cost. [2]
Why is a written contract important?
A written contract protects both you and the contractor by clearly stating the scope of work, timeline, materials to be used, payment terms, and other binding agreements. CSLB recommends reviewing the contract before signing. [2]
